1 The invention relates to a device for producing vibrations or agitations in liquid baths, particularly such as are used in the treatment of textiles.

Devices for producing vibration or agitation in the liquid in coppers have already been proposed, the object being to intensify the effect of the washing lye when the dirt particles are removed from the clothes. Such vibrating liquids may also advantageously be used in other types of treatment, for example, the dyeing of textiles and for other materials.

For the known vibrators operated electromagnetically or by means of compressed air, a special source of energy, such for example, as electric current, air conduits or the like must be provided to which the vibrator is connected. Such apparatus can be moved only to a limited extent, and requires in many cases fairly long conduits and special connections. Also the vibrators are bulky and expensive.

According to the invention, these disadvantages are avoided in that a burner, having an oscillating gas column and provided with means for transmitting the gas vibrations to the liquid, is used as the vibrator. It is known that such burners require only a tank filled with fuel as the source of energy. Such a vibrator may easily be connected to the bath and erected together with it at any desired place, as it requires no conduits connecting it to a distant source of energy.

It is of particular advantage that the burner can be used at the same time both as the vibrator and for heating. In this case the burner-system consisting of combustion chamber, gas channels, a transmitter for the vibrations and in a given case a sound absorber, is partly or wholly used for heating the liquid in the bath. This may be effected either by immersing individual parts of the whole system in the bath, or by using the gases for heating the bath container from the outside.

When a sound absorber is used, this also may be used for heating the bath. When an outer jacket is used for heating, this may serve at the same time as a sound absorber by being correspondingly constructed, and sub-divided so that a special sound absorber is not required.

The invention is diagrammatically illustrated by way of example in the accompanying drawings.

Figure 1 is a longitudinal section of a container and burner,

Figure 2 is a longitudinal section of a modified construction.

In the construction according to Figure 1, the bath liquid I02 is provided in a container IN. The burner-system with vibrating gas column is only drawn diagrammatically. Air and fuel are fed through the conduits I03 which extend into the combustion chamber I05 through a blow-back stop I04. The mixture in this combustion chamber is vaporised in synchronism with the vibrations of the gas column in the gas conduit I05 ber. piston in this conduit when passing through according to the natural vibration of the conduit The ignition of the burner, the relativej sizes of the parts, and the construction of blow-' back stop I04 may all be as illustrated and described in French patent No. 901,025, issued October 23, 1944.

In the gas conduit I06 provided within the bath IN is inserted a vibration transmitter which in the illustrated construction consists of a platelike enlargement I01 closed externally by a membrane I08 and provided with a perforated closing cap I09 for protecting the membrane against contact with the material to be treated, which is in the bath. The membrane I08 is set into vibration by means of the gas column vibrating in the conduits I06 thus transmitting the vibrations to the liquid in the bath. I I0 is a sound absorber installed in the conduit I06.

In the construction illustrated by way of example in Figure 2, 203 are the feed pipes which lead into the combustion chamber 205 through the blow-back stop 204. To the combustion chamber 205 is connected a gas conduit 206 constructed as a serpentine-heater, part of which extends within the bath 202 in the container 20I and the other part of which extends through the container wall and outside it. The vibration transmitter is provided in the portion provided at the outside, and consists also of a conduit enlargement 201, the membrane 208 of which is inserted in the container wall to form part of the bottom of the container. The membrane 208 is also protected from contacting the material to be treated in the bath by means of a perforated closure cap 209. When the gases have left the vibration transmitter, they are passed into a jacket 2I3 surrounding the liquid container 20I, and thus used further for heating the bath 202. In given cases the jacket may be so constructed, for example by being sub-divided into several individual spaces through which gas flows, that it serves at the same time as a sound absorber. The
